Hide code on lov

I have a dynamic lov. Wth lots of values - so I use a popup lov with a search option. cool.
It comes up nicerly and a user can click on the value they want. Unfortunately this then populates the apex-form with the number not the display value. So the user is surprised that what they picked in not on the form. Anyone know a simple way around this?
I was thinking of having a before insert trigger call a procedure and get the number...maybe too complicated!? Is there any other way around this?
In a sort of realted problem i now I have lov tables I cannot make a interactive report and form on the table as in order for the users to know what they are looking at they need the table to be joined to various lookups...a view is also problematic. I'm beginning to wonder about storing the data directly in the table and having a procedure on the lov table that will update the other 3 or 4 tables if the value in it is changed....nasty or at least unusual but maybe its my best simplest option given that there are never likely to be a huge number of tables usig these lovs?

Use popup key LOV (displays description returns key value).

Javascript To Hide/Show Complete LOV Item On Page

Hi All,
I am trying to show/hide a page item which is a LOV page item type. I was using the $f_Hide_On_Value_Item which does not hide LOV image. What should I use to accomplish this ? It has to implemented in Javascript. Any help appreciated ...
Tom

Hello Tom,
>> Are there other options ???
There are usually other options :)
Scorpio idea is a good start, although I‘m not sure his code cover the label of the LOV item. I think for that you should go one level up in the DOM. Using the ID suggestion he gave you, try using the following line:
$x('popUp').parentNode.style.display = 'none';That should hide the entire ‘tr’ the LOV item is on.
Hope this helps,
Arie.

Can I have a PL/SQL code for LOV

Hi,
I apologize for this dumb question. I have been so out of touch with dev (almost 8 years). Plus new to pl/sql.
I am creating a status report application. On the dashboard, I currently have some metrics (horizontal charts). I wanted to expose these metrics based on filter.
I had created 2 filters. The first one will identify the type (Week, Month, Qtr or Year) and the 2nd filter would be based on the type. For e.g. if I select Month as type, the 2nd filter should show May-12, April-12 etc. Once I select the 2nd filter, I should use them to show the appropriate metrics. The metric that I currently have would show all the projects that users have worked on during the week/month/qtr or year (depending on the 1st and 2nd filter).
On the dashboard region, I added a condition to check if the value for both 1st and 2nd filter is not null. This allows me to show the dashboard only if the 2 filters have been selected.
For the 2nd filter, I need to write a PL/SQL code to show the LOV.
I am assuming that the pl/sql would return a SQL query. The SQL query will be based on week, month etc. Is that right?
Thanks

Hey all,
Is there an easy way to turn the code navigator icon off in code view? It likes to pop up at the most inconvenient times and hides parts of my code from me. Do I have to disable 'all' tool tips? Please help. Thanks.

Custom code for LOV generation in Custom.pll

Interactive objects/gaming code within LOVE magazine iPad app. How do they do it?!

I am referring to a folio within the LOVE Magazine iPad app, which is free in most part. It is called 'Kusama & Louis Vuitton'.
When a finger is placed on the iPad a randomized ball appears, then this may be 'flung' about the page and it interacts with other balls created. On some pages they give the balls some sort of gravity simulation meaning they always fall downwards.
ANY help on finding out how to start playing with these interactions and getting them onto the iPad would be amazing.
Thanks.

Its gonna be tough using HTML and Canvas probably. Here is an article outlining implementing gravity in HTML5...

Hide Code Group code as selection

When we develop Code Groups and Codes, after a period of time the Code is no longer to be used. I understand that it can not be deleted as it has usage, but why can't one flag similar to the Code Group itself so it will not be visible for selection. Right now we change description to DO NOT USE, but users still select code.

Hi,
It is possible to delete the catalog codes inside the group.
For that, first you have to define your own catlog type (as SAP recommends not to change the settings for the SAP defined catalog types).
Procedure:
- Define catalog type say 'Z'
- In config set the check box Deactivate. (Read F1 help on this checkbox)
- Now define the codes for this type in QS41.
- Use the code somewhere (e.g. Notification)
- If u check QS41 again, it will have usage indicator.
- But you can delete the entry ignoring the warning message.
Let me know if this fulfills the reqmnt.

PL/SQL code problem for LOV

Hi,
I have developed an application using Apex 4.0
Now, i am trying to make a LOV for two columns in my table. Say column A and column B.
Column A has four different values under it say x,y,z,w and column B has around 3 different values say 1,2 and 3.
How do i write a code for LOV for A and B.
SO that it shows me a drop down list for each and then display results accordingly.
Thanks

user13280446 (mind setting your name?),
The fix for this error is to find the subquery in your SQL that's returning more than one row; generally, you'll want to fix the subquery to return only one row, though in some rare situations it's appropriate to change an = to an in clause.
Example:
select *
from a_table a
where a.col1 = ( select b.col1
                 from b_table b
                 where b.col2 = 42 );Unless b.col2 is guaranteed to be unique (either PK or enforced through a unique constraint), sooner or later that subquery is going to return more than one row, producing the error you're seeing. These variations will all avoid this, though which one (if any) is/are correct is dependent on the data:
select *
from a_table a
where a.col1 = ( select min(b.col1) -- Ensure one row returned
                 from b_table b
                 where b.col2 = 42 );
select *
from a_table a
where a.col1 in ( select b.col1
                 from b_table b
                 where b.col2 = 42 );
select a.*
from a_table a,
    b_table b
where a.col1 = b.col1
    and b.col2 = 42;This is a very contrived example, of course, but without seeing the SQL for your LOV, we can't be any more specific than that...

Show/hide based on Multiple selections in a select box

it works great as long as only one value is selected:
if you highlight the ARRAMO value the DUNS field appears...
if you highlight anything else the DUNS field disappears...
but if I highlight both ARRAMO and another field, I want the DUNS to SHOW and it DOESNT..
how do I fix this?
<script type="text/javascript" src="#WORKSPACE_IMAGES#jquery-1.3.2.min.js"></script>
<script language="JavaScript" type="text/javascript">

</script>
<script type="text/javascript">

Using LOV, you can have multiple selection.
For this you can write code in the KEY-LISTVAL trigger.
Create an LOV for store code.
In the text-item of store_code (where you want mul. selection), you assign the LOV to that item.
In key-listval trigger,
You can have something like
Declare
m_val varchar2(1000);
a boolean;
Begin
m_val := :store_code;
a := show_lov('STORE_LOV');
if a then
If m_val is null then
     m_val := :store_code;
else
      If instr(','||m_val||',' ,||','||:store_code||',') = 0   /*check whether store code already selected, to get excat string comma is concatenated*/
         m_val := m_val||','||:store_code;
      end if;
end if;
end if;
:store_code := m_val;
End;Note :To check for validation, additional coding is required...

Error While Running LOV

Hello,
I am using APEX 4.0.1.00.03 and 11g DATABASE, and I'll explain my problem on the following lines.
I've started using functions in PACKAGES to return results to my LOVS in APEX, so that I can change the code of LOV without having to make any change in the application (I've created a generic table type t_varchar_number). The problem is I've started to get this error:
"ORA-06550: linea 1, columna 71: PL/SQL: ORA-0947: no hay suficientes valores ORA-01007: la variable no está en la lista de selección ORA-06550: línea 1, columna 7: PL/SQL: SQL Statement ignored ORA-01007: la variable no está en la lista de selection".
Strangely it doesn't appear every time and if I push F5 a given number of times it will disappear and stop giving the error for a time. I've also placed a logging mechanism on the code so that I can see the query strings I use on my "execute immediate" instructions, when the error appears and there is no difference from when it doesn't give the error. Also if I run the string I place on the log manually there is no error.
On each LOV I use the following code:
select * from table(PACKAGE_NAME.function_name(args))
Can anyone help me out? What other steps can I take to try and track this problem?
Thank you,
Miguel

Hi Scott,
I'm also facing the same problem as Monika.
I have an LOV with the following query which returns 8774 records, when I copied and pasted those records into a text file it shows as 220KB in size.
SELECT
p.name d,
p.pers_id r
FROM people p,
people_contacts pc
WHERE SYSDATE BETWEEN NVL(start_date,SYSDATE) AND NVL(end_date,SYSDATE)
AND     p.used_by_orc = 'Y'
AND     pc.pers_id = p.pers_id
AND     pc.group_id IN ('ORC','SHARED')
ORDER BY 1
After searching the forum, I think there's a 32K limitation on the fetched rows in tabular forms, can you please let me know how to overcome this problem?
I'm selecting the persid in the (tabular form) SQL query updatable report.
I'm trying to display the field as Name instead of PERSID by changing it to select list(based on named LOV) or whichever way it can work.
Please help me.
Thanks in advance.

Hiding code in ABAP programs

I curious if in ABAP is possible to hide code.
What I exacly mean?
In other programming languages e.g. C++ when we want to hide some part of implementation, we just simple make an library (dll file) and we join it to complilation code.
Is included in ABAP similar functionality?`

Hi Tomasz,
Check this code:
This is not my own code.
PROGRAM ZHIDE NO STANDARD PAGE HEADING.
This program hides any ABAP's source code and protects it with a
password in this source code. So the first candidate to be hidden
should be ZHIDE itself.
After hiding, you can still run the abap (the load version is intact)
but it cannot be displayed, edited, traced, transported or generated.
If the ABAP is not hidden, the program hides it, if it is hidden, it
unhides it.
To execute this program, change the user name and password in this
source code first.

Code View Wordwrap Bug

In code view window, with wordwrap, dreamweaver hides code characters on the right edge of window.
It only hides 3-4 last character of the largest line.
Is it a bug? Does anyone notice it?

I have also faced this issue where if code's line is large and WordWrap is enabled, then it Dreamweaver CS6 actually wrapped it but hides 3 to 4 characters which is not select able or even view able. See the attached screenshot, you will see Dreamweaver CS6 hides some characters of my line which is definitely something wrong with the DreamWeaver.
Can anybody found the way to avoid it..??..I cant allow the WordWrap to be disabled and scroll it with that pathetic horizontal scroll.
